When you're mixing up a sweet strawberry daiquiri there's nothing more frustrating than a blender that doesn't crush up the berries just right. Who wants chunky strawberries in their drink? Not us. That's why we're in love with the BlendTec FourSide Jar, a square-shaped jar that forces ingredients off the walls and back down into the blade for better blended recipes. Sometimes, it's cool to be square.
